INTRODUCTION
S&S® cylinder torque plates simulate the stress cylinders experience when installed on an engine during honing operations. A cylinder that has been
honed between torque plates holds to its installed dimensions better than a cylinder honed without torque plates.
Torque plates for 41⁄8" and 41/4" bore X-Wedge™ cylinders can be used with either horizontal Sunnen® type hones, or portable hand held hones.
If a vertical Sunnen® type hone is used, a holding fixture will have to be fabricated. A boring plate/honing fixture is not available from S&S for use
with 41⁄8" and 41/4" bore torque plates.

NOTES:
Always observe professional practices and wear safety glasses and protective clothing when operating machinery.
•
S&S torque plates are hardened and must not come into contact with cutter or honing stones during operation.
•
Torque values for torque plate hardware may vary significantly from values used to assemble engine.
•
Improper operation of machinery or fixtures can damage motorcycle parts, tools and/or machinery components.
Improper operation of machinery and associated equipment can cause personal injury to operator and others nearby. Contact a professional
mechanic if unsure of correct procedure.
TORqUE PLATE INSTALLATION
The first step of any boring or honing operation is installing and torquing the plates to the cylinder. See Picture 1.
CAUTION
WARNING
1- Place base gasket over end of cylinder spigot.
2- Place bottom torque plate over end of cylinder spigot. The base end has two relief cuts. One side is printed 41⁄8" and the other is printed 41/4".
Place the side up that correlates to the cylinder being measured.

Torque plates must be used with new gaskets.
Used to keep assembly from turning when horizontal honing.
